Avatar, Star Trek & Watchmen
Saw Avatar again today. To blazes with anyone who says the plot is simple. There are a mass of metaphors in there and everyone is complete and free standing. It has 9/11, the extermination of indigenous populations, the Iraq War and a pagan/environmental metaphor deeper and more beautifully expressed than I have ever seen and each of these themes are explored to their natural conclusion. From the corporate guy who cuts the feed when it gets messy (just like the news channels during war) to the total immersion in the middle of a 3D 9/11 type catastrophe to the interconnectedness of the whole eco-system, it is perfectly written.
And yes, I still cried when mother nature herself kicked ass. I don't think I'll ever not cry at that scene.
